MITER-BOX.

Specification of Letters Patent.

Application filed May 13, 1908.

Patented Feb. 8, 1910.

Serial No. 432,698.

T o all whom t may concern.'

Be it known that I, NnLs G. NELSON, a citizen of the United States,residing at Rockford. in the county of lVinnebago and State of Illinois,have invented certain new and useful Improvements in Miter-Boxes, ofwhich the following is a specification.

This invention relates to improvements in miter-boxes, and it lconsistsin certain peculi arities of the construction, novel arrangement, andoperation of the various parts thereof, as will be hereinafter moiefully set forth and specifically claimed.

The principal object of the invention is to provide a miter box whichshall be simple and inexpensive in construction, strong, durable andeffective in operation; and so made that parts thereof may be adjustedwith the greatest accuracy and firmly held in their adjusted positionsso that the pieces of wood may be cut or sawed at any desired angles.

Other objects and advantages of the invention will be disclosed in thesubjoined description and explanation.

In order to enable others skilled in the art to which my inventionpertains, to make and use the same, I will Vnow proceed to describe it,referring to the accompanying drawing; in which- 'Figure 1 is a top planview of the invention.y showing a portion of the removable cutting`section broken away to disclose a part of the main frame of the device;Fig. 2 is a bottom plan view; Fig. 3 is a front view partly in elevationand partly in section; and Fig. L1 is a transverse vertical view takenthrough the middle of the device.

Like numerals of reference, refer to corresponding parts throughout thedifferent views of the drawing.

The reference numeral 1 designates the main frame, which is preferablymade of open iron work; and has secured to its upper surface and endportions horizontally disposed platform sections 2 and 3, the adjacentends of which are cut away at angles to one another as shown in Fig. 1of the drawing, and each of said adjacent ends of said sections isformed with an undercut f1 to engage correspondingly shaped edges of aremovable section 5 which, when in place, will rest on the middleportion of the upper surface of the main frame 1 and will serve toassist in supporting the material to be sawed. The lower portion of eachof the platform sections 2 and 3 is provided near' its outer end with apair of feet 6 transversely arranged with respect to the box, and areemployed to hold the same at a suitable distance above the work bench onwhich the miter-box may rest.

Secured to the rear portions of the platform sections 2 and 3 areupright back sections 7 which are held in their upright positions bymeans of standards 8 extended upwardly from the feet G and also bymeans' of bars 9 extended upwardly from the main frame 1 near the innerends of the sections 7 of the back. Extended horizontally from each footG is a projection 10 which supports a thumb-screw 11 which is adapted toengage a slide 13 which is located in longitudinally extended grooves 12formed in the lower surfaces of the sections 2 and 3 near their rearedges. One of the ends of the slide 13 is provided with an uprighttubular portion 14 having a slot 15 in its face. Within this tubularportion is located a plunger 16 which is adjustable vertically withinthe tubular-portion, and is held when adjusted by a thumb-screw 17carried by the plunger and guided in the slot 15 of the tubular portion.To the rear middle portion of the main frame 1 is pivotally secured thesaw carrying frame 18 which is horizontally located beneath the mainframe and connected thereto by a bolt or pivot 19 which; as is shown inFigs. 2 and el of the drawing7 is' located near the rear end of theframe 18, which frame in front of said' pivot is preferably of askeleton type having two spaced apart sides connected together at theirfront ends. Pivotally secured between the sides of the frame 18 neartheir front ends is a latch 2O which has at its front end a downturnedfinger 21 or hooked portion which may be readily grasped by the hand ofthe operator. Extended across the frame 18 and secured thereto slightlyin front of the pivot 19 is a bar 23 which supports a bow-spring 22, therear ends of which are connected to the rear portion of the frame 18 andthe front end of which engages the rear part of the latch 20, so as tonormally press its rear end upwardly.

The main frame 1 has on its front portion a segment 24 which is locatedconcentric with the pivot 19 and has in its lower surface a series ofnotches or recesses 25 adapted to receive the rear end of the latch 20in order to lock the frame 18 at the desired position to the main frame1 of the box. As shown in Figs.2 and?) the segment 2st is provided witha recess near each of its ends and with a similar recess midway betweensaid end recesses, and has on its outer surface a horizontally extendedledge 26 for the purpose to be presently explained. Each end of theframe 18 is provided with a vertical opening to receive reduced portionson the lower ends of the saw guide supports 2T and 28, which are tubularin form and are provided with slots 29 for the reception and operationof the saw-blade. The reduced portions' of the supports 27 and 2S may berigidly held in their respective openings of the saw carrying frame 1Sby means of small set-screws located in the ends of said frame.Vertically and movably located in each of the supports 2T and 2S is asaw-guide 30, each of which is preferably hollow and tubular in form,and has a longitudinally extended slot 31, the lower portion of which isenlarged and open to permit of the movement of the teeth of the sawwithout contacting with the sides of the guides or their supports, andto also permit of the discharge of sawdust. carried by the saw in itsmovements back and forth.

Extended horizontally through the lower portion of the support 27 and inscrew engagement therewith is a rod 32 which extends rearwardly to nearthe front surface of the segment 24, and normally rests at its rear endon the upper surface of the ledge 26 of said segment. This rod has ahead 33 on its outer end by means of which it may be turned, and nearits inner end is extended through an aperture in a guide 34 on the uppersurface of the front portion of the saw carrying frame. This rod 32 isemployed for the double. purpose of fixing the frame 1S to the segment21 at any desired point between the notches 25, as well as for moresecurely holding the frame 18 to the main frame at said notches and,besides, to relieve the pivot-bolt 19 of the great strain itwouldotherwise be subjected to, for, as before stated, the inner end of therod 32 will normally rest on the upper surface of the ledge 26, thussupporting the front part of the sawframe.

By the employment of the removable section 5 formed with its end edgescorresponding in shape to the inner ends of the sections 2 and 3 of theplatform of the miter-box, it is apparent that it can be caused to fitclosely in the space between the sections 2 and 8 so that its uppersurface will be flush with the upper surfaces of said sections toproperly support the material to be sawed, and that by using theremovable section an ordinary saw can be used in connection with thedevice.

It is apparent that the plunger 16 can 'be adjusted vertically above theplatform sections so as to act as a stop to the material being cut, andthat the slide 13 can be located at either end of the miter-box and heldin the desired position by either of the said screws 11 therefor.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters-Patent, is-

In a miter box, the combination with the platform sections, comprisingthe end sections and removable middle section, and the vertical backsections, ofthe feet to which said end platform sections are secured,said feet having integral therewith upstanding bars, or back-supports S,a central iron-work member 1 which is also provided with integralupstanding bars, or back support-s 9 and an integral notched quadrantand pivotbearing for a radial arm, said end platform and back sectionsbeing united, secured together and supported relatively to each other ina single rigid member by said central iron-work member and its integralbacksupport bars 9, a groove extending longitudinally in the undersurface of said platform sections from end to end of the frame, a slidein said groove which is supported against displacement therefrom by saidfeet and iion\vorlr member, a vertically adjustable stop in one end ofsaid slide, and arranged to project above the platform, said slide andstop being reversible to place said stop at either end of the frame orplatform, a radial arm pivoted in said pivot bearing, the slotted sawguide supports mounted on said arm, a latch on said arm provided with ahooked finger portion to be engaged with either of the notches in saidquadrant, and a screw clamping rod 32 mounted on said arm and providedwith a head 33 projecting from the end or exposed portion of said arm,said rod arranged to bear against said quadrant to hold said arm in anydesired intermediate position between the notch positions.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
